Free Comic Book Day hits comic shops across the land this Saturday, May 5. And for FCBD, Dark Horse Comics is offering a free Star Wars/Serenity doubleheader penned by Dr. Horrible's Sing-Along Blog co-creator Zack Whedon. Courtesy of Dark Horse, here's an exclusive first look.

You can read our previous rundown on how artist Dan Dos Santos designed the cover here, find out everything about FCBD at this link, and behold a synopsis of this issue:

Han Solo and Chewbacca have a falling-out after a deal with a shady customer goes bad. When the client gets designs on the Millennium Falcon, Han and Chewie present a united front that can't be beat! "Mal" Reynolds, captain of the outlaw vessel Serenity, is no stranger to jobs gone wrong. But when the chips are down, he's able to rely on an amazing, odd, and diversely talented crew for help!
